LV301024179CN - Beijing, flight departure. Is it in a flight to Shanghai? What's the reason for the route change?

you can't know what is the next destination after departure of Beijing. China Post . It might be to Shanghai, might be to London or Frankfurt whichever has cheap flight space routing to Israel. It is very likely that the parcel will keep transiting through different middle airports. So knowing the next airport makes no sense.

You just need to wait a couple weeks to see next scan or update after it arrives Israel airport. Once the parcel is scanned by Israel post, then it means you will get the item very soon.

I mean, I can know. It says this in the tracking number.

Beijing, leaving Beijing Terminal, next stop, Shanghai Jiamin Processing Center (via transit)

And according to this site's tracking status it just arrived Shanghai.
2021-10-16 06:10:15 Shanghai Arrival at Regional Sorting Center

So what I was asking is there a reason for the route change to Israel? Is it supposed to be faster? Because all the time it shipped through Zhengzhou and not Shanghai.
